Frequently asked questions
How is FD maturity calculated?
Maturity = deposit times (1 + r/n) raised to (n times years), where r is the annual rate and n is how many times a year interest compounds. More frequent compounding gives a slightly higher maturity.
How often do banks compound FD interest?
Most Indian banks compound cumulative fixed deposits quarterly, which is the default here. Some products differ, so check your bank. You can switch the compounding frequency to match.
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate, and banks deduct TDS above a threshold. This calculator shows the pre-tax maturity value.
FD or a debt mutual fund?
An FD gives a guaranteed rate and capital safety up to deposit insurance limits. A debt fund can be more tax-efficient over long holding periods but carries some risk and no guarantee. Compare the post-tax return for your situation.
